Im just interested in the paticulars of chocolate being a derivative of black i have been studying genetics on my own for awhile and have never came across that wanted to see if you could point me in the right direction thanx

"(As) - DOMINANT BLACK: This allele produces uniform coverage of dark pigment over the entire body. Its action is expressed in all dogs with black or brown coats. The (As) allele is almost completely dominant over others in the A series. The black color ranges from pure black to a black with a brownish cast (seal). Geneticists are uncertain if the allele is incapable to produce pure black without additional help from another locus, or if the brown cast indicates a heterozygous allele."
... "The red nose in our breed is produced from the Locus B pair with the homozygous recessive (bb) genotype in combination with the (Ay-) genotype."
"Question # 3: Where does the chocolate color come from?
The chocolate color comes from the Locus B pair with the homozyous recessive (bb) in combination with the (As) allele. The dilution gene (dd) will also modify this dark chocolate to a light or almost milk chocolate. In most cases, the nose color is also light brown or as we say ‘chocolate/red nose’."

No problemo
i have read that material a fews times so being that chocolate comes from Locus (B) paired with the recessive (bb) and dominate (As). Two being Dominate black is there reason behind saying chocolate is a derivative of black ?

It is a mixture of red/rednose (bb) and black (As).
Rather than the black completely dominating, it "combines with" to form a chocolate/rednose ... which is neither a true black dog ... nor a true rednose dog ... but a combination of both.

So jack I know we talked about this on another post.... all things being equal should I breed my black or red bb to that bitch to get that cola color? Its a daughter of blaze.

Coca Cola was a fierce bitch, with awesome body strength, who TRIED to finish ... but she never had the ability to "finish with one hold" like Silverback, nor did she have anywhere near his intelligence or athleticism. She was just awesomely strong, had bad intentions, and was game as a bitch could be.
Of the Coca Cola dogs I had, only Stormbringer could kill a dog with one throat hold, and while his awesome body strength came from Coki, his his intelligence and pit savvy came from Poncho. None of Stormy's littermates could do this (although his brother, the blond Crews' Sandy, threw dogs that would finish). Coki's daughter, the blonde Red Sonja was pretty much just like Coki. Coki's daughter Bandana was super-fast and was always looking for the guts or stomach ... and she was a red/rednose ... but, strong and relentless as she was, she was not as awesome a finisher as either Stormbringer or Silverback. Her best son, Ch Vengence, sired by Silverback's sire, Ouch!, was a chocolate ... and he was a tactical ace, with a heavy mouth, but I never heard of him being a total finisher, though he did break the windpipe of the last dog he faced. (Likewise, Vengence's blonde brother Techno threw the devastating Ch Tulipa (4xW, 4xBIS), but she was a buckskin. So the chocolate/seal color is not as dominant in Coki dogs (for me anyway) as it was in Silverback. The trait of finishing in Silverback dogs has been 100% seal so far.
Therefore, to answer your question, my # 1 priority would be THE TRAITS not the color. Your Ch Blaze was a chocolate, and he is obviously the standard you're after, as he too was a vastly better dog than Coca Cola herself. Color-wise, black is closer to chocolate (especially if the "black" is really a dark seal), so I would lean that way ... unless the rednose was the better dog. For me, with Coki dogs, Stormbringer was by far the best ... and he was a red/rednose and a light-years better all-around animal than his mother Coki. In short, I am not sure I would make Coki the standard, as she was able to produce better dogs than herself. I would make the ace the standard ... though it is hard for an ace to be able to produce better than himself.
So I would go with TRAITS first, and then (if all else was equal) go with the color that best falls in line with the BEST dog close up that you're trying to breed to.

Would have loved to breed a daughter of stormbringer to machobuck, we almost did it, I believe we discussed it at one time or another.
That should be another addition to the "If Only" chapter in The Hollingsworth Dogs book ...
